i have owned and used model 43uwx10b hitachi projection tv for five years with no trouble. recently, when i turn it on, the red power led on the front of the unit flashes and there is a quiet clicking sound from within that keeps time with the flashes. naturally there is no picture or sound. the normal condition would have been a steady red led. does anyone have advice?
You could have a problem with the fluid leaking down onto the printed circuit boards from picture tubes, or possibly a power supply regulator problem, or a short in the horizontal circuit. Without the knowledge of how each circuit works with each other, this will not be a job for you to attempt I'm afraid. Good Luck, and please let us know if you get this set repaired, and what was found bad.
